Adamson (United Kingdom) - AllCarIndex

Adamson was a British automobile manufacturer active from 1912 to 1924, based in Enfield Highway, Middlesex. The company, officially known as R. Barton Adamson & Co. Ltd, initially produced cyclecars, a type of lightweight vehicle designed to be economical and efficient. The early models were equipped with a 2-cylinder Alpha engine, a 3-speed gearbox, and utilized a belt drive system. Notably, the design featured an underslung frame, which contributed to a low profile appearance.

In the post-World War I era, Adamson's offerings became more unconventional. The later models were characterized by a unique body design that resembled two sidecars positioned side by side, with the driver seated in the offside compartment. These vehicles were powered by a 1075cc 2-cylinder British Anzani engine and employed a chain drive system. Additionally, a light car variant featuring a 1330cc 4-cylinder Alpha engine was produced until 1922, showcasing the company's brief but diverse automotive development.
